To take a random sample, choose an area, use a random number generator to avoid bias, use an appropriate sampling technique, and repeat the process as many times as possible to reduce chance.
Pentru a preleva un eșantion aleatoriu, alegeți o zonă, folosiți un generator de numere aleatoare pentru a evita biasul, utilizați o tehnică adecvată de eșantionare și repetați procesul de cât mai multe ori posibil pentru a reduce șansele ca rezultatele să fie datorate întâmplării.
